How about something like this:

\version "2.22.2"

subPPMarkup = \markup { \normal-text \italic { sub. } pp }
subPP = #(make-dynamic-script subPPMarkup)

\midi {
  \context {
    \Score
    dynamicAbsoluteVolumeFunction =
      #(lambda (dyn)
         (if (equal? dyn subPPMarkup)
             0.3
             (default-dynamic-absolute-volume dyn)))
  }
}

\score {
  {
    c'8\pppp\< d'8 e'8 f'8 g'8 a'8 b'8 c''8 |
    c''8\fffff b'8 a'8 g'8 f'8\subPP e'8 d'8 c'8 }
  \layout { }
  \midi { }
}
